How to clean maggot from an open wound?

Maggot is a larvae or young form of the fly. Actually, the habitats of maggots are in water, old vegetables, meat , fruit, also in dead animal, but in some cases they also may live in living creatures such as pets and human. Yet the flies cannot just lay down their eggs wherever they want on human body. Usually, the odor which is came from an open wound (especially the infected ones) can attract flies, then followed by they lay their eggs which develop into maggots in the area.

Does maggot help heal wound?

Although maggots are disgusting and creepy, they are not always bad. In medical care, maggots are intentionally put on an open wound. They are used for wound healing treatment called maggots therapy. The common maggots which are used for this medical therapy are maggots of certain flies such as Green Bottle Fly or Nothern Blow Fly. The maggots are left to stay in the wound for two or three days (depends on the size and the infection of wound) covered by a dressing.

The common wounds which may be healed by this therapy are : venous statis ulcer, pressure ulcers, neuropathic foot ulcers, and non-healing necrotic skin and soft tissue wounds.

How useful are the maggots in this therapy? At least there are three advantages of this maggots therapy :

Debridement

The wound is difficult to heal because of infection at the wound and the skin around it. But in this therapy, maggots eat the dead and infected tissue, then debride the wound by secreting proteolytic enzymes. After the therapy, the only thing left is a clean wound.

Des-infection

They prevent and kill the bacteria from the wound.

They promote healthy tissues to grow quickly.

It is important to consider that the maggots which are used for this therapy are not the maggots you got from letting some flies penetrate their eggs on your wound, but the medical maggots which are provided specially for this purpose.

Does maggot carry disease?

People may think that since maggots are young flies, they carry disease to the wound where they live in. Actually maggot itself does not carry any disease, on the other hand the flies do.

Although they does not carry disease, an infestation called Myiasis may occur. Infestation occurs when an infected open wound attracts flies to lay their eggs into the wound, then those eggs become maggots, turn into flies which then repeat the life cyle on that wound. If the maggots are not removed or cleaned from the wound, this infestation may cause a further infection
